Campus Scene IN T HE SPOT LIGH T HotTips This Month Building Systems Mass Equals Energy ALBERT EINSTEIN DESCRIBED ONE relationship between mass and energy as E=mc2. But in today's schools there's another relationship — the one between high-mass wall construction and resulting energy savings. Schools are typically constructed using precast, site-cast, cast-in-place, or concrete masonry units (CMUs). Precast concrete walls are cast in a plant, trucked to the site, and set in place with a crane. Site-cast tilt-up walls use formwork that is built on the site and filled with concrete, which then hardens before being lifted into place via implanted metal hooks using a heavy crane. Cast-in-place walls use either hand-built wooden forms or factory-extruded, lightweight, interlocking poly materials that are then filled with concrete, usually from a concrete pumping truck. Wood formwork is removed once the concrete has hardened, while interlocking poly forms are designed to remain and become exterior and interior finishes. CMUs (or "cinderblocks") are trucked to the site and set in place, one at a time, by masons, then filled with concrete. When completed, these are all considered high-mass walls, and they function like energy batteries. More than providing something to hold up a roof, they store and release heat and cold. During warm daytime periods they slowly absorb heat rather than transferring it to the building interior. During cold weather the reverse occurs. To varying degrees, the resulting buffer effect reduces the demand for energy consumption to heat or cool the building interior. This means lower energy bills or even smaller, less expensive heating and cooling mechanical systems. In determining which type of high-mass wall construction is best for a project, consider key points such as speed of construction, availability and cost of skilled trades and heavy equipment, site access and working room, and aesthetics. An architect, in conjunction with manufacturers, and contractors experienced in school construction, can help evaluate the best method for your project.

Edison Exploring $10K Bachelor's Degree Edison State College President Jeff Allbritten announced that the Ft. Myers, FL-based College is working to offer a four-year degree for $10,000. The announcement was made during the regularly scheduled Board of Trustees meeting in January. On average, a fouryear degree from Edison State College costs approximately $13,000. "Late last year the Governor issued a challenge to create a baccalaureate degree program that would cost $10,000," says Dr. Allbritten. "We have accepted his challenge and are now working to try and make it possible." Edison State College is targeting the Bachelor of Science degree in Secondary Biology Education. "With this degree in mind, we are now exploring ways to find alternative funding sources to cover the difference. There is a high demand for secondary biology teachers, and this degree would be an excellent avenue to give our students an even better value while also addressing a local workforce need," says Dr. Allbritten. Anne Arundel CC Library Expansion Is Complete A $17.2M expansion and renovation of the Andrew G. Truxal Library at Anne Arundel Community College in Arnold, MD, was recently completed. One of the three original buildings from the 1968 campus, the Truxal Library is now nearly doubled in size and completely upgraded technologically. The expansion, undertaken by architecture, engineering, and interior design firm EwingCole, added 32,000 sq. ft. to the south side of the existing 45,000-sq.-ft. structure. The new twostory glass façade, emphasizing new technologies, is the first image of the library seen by visitors to the campus. Inside, a double-height space contains individual and shared computer workstations and surrounding group study rooms for collaborative learning. The full-height glass is embedded with a COLLEGE PLANNING & MANAGEMENT / FEBRUARY 2013 ceramic pattern to control sunlight and reduce glare on the computer screens. The project design includes many sustainable features to reach the goal of LEED Silver certification, including a vegetated roof with a landscaped rain garden to contain storm water run-off, an automated lighting system based on occupancy and available natural light, and extensive use of building products and interior finishes made from recycled materials.
